Austrian school

Named essentially after the work of three economists that taught the same course at the University of Vienna:

-Carl Menger, whose main contribution to economic science is the theory of marginal utility;

-Friedrich von Wieser, who formulated the idea of opportunity cost;

-Eugen von Böhm-Bawerk, who contributed to economics with his studies on the nature of capital and interest rates.

Ludwig H. Edler von Mises and Friedrich A. von Hayek are considered followers of this school, and also as links to the Chicago School.
